Enable Strict Replication Consistency

Supposed a domain controller get disconnected from the replication topology for an extended period and then later on reconnect it. You need to make sure that no outdated Active Directory objects can be replicated within the forest.

Use regedit command and go to: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\NTDS\Parameters
Create a Strict Replication Consistency with REG_DWORD data type. Set 1 as the value.

This setting ensures that no outdated objects are reintroduced into Active Directory Domain Services (AD DS).
You need to set it on all of the Domain Controller within the Forest.

Error when burning CD

Have you ever get an issue when trying to burn some files to a CD/DVD?
In my case I got error writing Lead-In when trying to burn some file using UltraISO on my IBM T42 CD ROM (HL-DT-ST RW/DVD GCC-4242N). I can use it to read any CD/DVD with no issue.
I try to change the burner software to Nero but got similar error too. Try to lower the burning speed with no luck.
Previously I remember that I can burn a CD with that CD ROM, somehow it's just stop working.
I try to search for a driver update but cannot find any. A firmware update maybe available but I think that's too much for the issue.
Finally I try to clean the lenses. Just wipe it with a clean tissue, try to burn, and it works.
